FUEL-CONTROL lDlElllCE.

To all whom t may cof/were.'

Be it known that l, Genaro A. Honou- 'rALrNe, a citizen of the United States, and a resident of llndianola, in the county of Warren and State ot llowa, have invented a certain new and useful Fuel-Control Device, of which the following is a specication.

rlhe object of my invention is to rovide a fuel control device oil simple, dura le and inexpensive construction. v 0

With this and other objects in view, my inventionconsists inthe construct1on, ar rangement and combination of the various parts of my device, whereby the ob]ects contemplated are attained, as hereinafter more iully set forth, pointed out in my clalm, and illustrated in the accompanying drawin s, in which:

igure 1 shows a side elevation `of a` portion of a tractor engine equipped with a fuel control device embodying my invention.

Figure 2 is a detail, sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a detail, sectional view taken on the line 3 3 of Fi re 1.

Figure d is a detai sectional view taken on the line d-d or Fi re 1.

Figure 5 is a detai sectional view taken on the line 5-5 of Figure d; and

Figure 6 is a perspective view of the valve l structure forming part of my device.

My improved fuel control apparatus is designed as an improvement upon the fuel control structure of a well-inlown tractor, the Fordson, and l have shown my device 'illustrated in connection with portions of such a tractor. y'

In the accompanying drawings, ll have used the reference numeral 10 to indicate generally an engine body. The enginel has an intake manifold 11 and the' exhaust manifold 12. Suitably supported, for instance above the engine, is a large kerosene tank 13.

Supported rearwardlyv with relation 150 the manifolds is a asoline tank 1d. Conveniently mounted 1s a carburetor 15.

The engine is provided with an air washer 16 and with an air pipe 17 communicating therewith and with the carburetor.

Above the intake manifold 11 is a mixing chamber 18. An air pipe 19 leads from the washer 16 through the air valve casing 20 to the mixing chamber 18.

1n the tractor under consideration, before the same is equipped with my invention, there is a pipe 21 shown in dotted lines in Figure 1, leading from the gasoline tank 14% directly to the mixing chamber 18, through what may be called the' gasoline control valve 22. rllhe valve 22 can be turned to position to permit gasoline to pass from the pipe 21 to the mixing chamber 18 or inayk be turned to position to prevent such ow. v

0n the tractors under consideration, a pipe -23 leads from the tank 13 through a sediment collector 211 to the carburetor 15. From the carburetor 15, the mixture passes through a fuel pipe 25, which is received within a casing 26 to a coil 27 in the exhaust manifold, and thence upwardly through the pipe 28 to the mixing chamber..

The valve 22, which forms no part of my invention, and isa part of the standard equipment of the tractor mentioned, is so constructed as to cut 0H' the kerosene passage from the lpipe 28, when said lvalve stands in position for admittin gasoline lghrough the pipe 21 to the mixing chamtiti rllhe tractor is intended to be started on gasoline, and after it has run for a short time to be run on kerosene.

llt will, therefore, be noted in the operation of the tractor, not equipped with my apparatus, that the valve 22, which is capable of operation from the tractor seat, is turned to position for admittinggasoline through the pipe 21 to the mixing. chamber, and in that position shuts ed any inflow of kerosene. The tractor is run on gasoline until it is warmed up, and then the valve 22 is manipulated for shutting od'the gasoline flow, and permitting the now of kerosene through the pi e 28 to the mixing chamber.

he valve 29 is provided just below the tank 13.101 shutting od any flow of kerosene from such tank.

When the user leaves the tractor to stand any length of time, the valve 29 should be closed and the valve 22 should be turned to its neutral position.

@ne undesirable feature of the structure heretofore used arises from the fact that if the tractor is run on gasoline for too long a period, the coil 27 is likely to burn out, and this frequently occurs.

The purpose of my invention therefore is -to provide a modified structure, `which will reduce the number of operations necessary for running the tractor, and therefore reduce the amount of laborl and also the amount of care that must be given for operating the tractor, and also to rovide a structure, whereby the danger oi) burning out the coil 27 is wholly avoided.

My structure also reduces the amount of material necessary for building the fuel control equipment.

Where my device is employed, the pipe 21 and the valve 22 are done away with.

A casing 30 having a three-way valve 31 is arranged with one nipple 32 connected with the carburetor. Another nipple 33 is connected with .the pipe 23 and a third nipple 24 is connected with a pipe 35 leading from the gasoline tank 14.

It will thus be seen that while I have simply added a three-way valve and done away with some parts, the total combination which has been produced, is entirely different from that heretofore used.

With my new structure, the valve 31 can be turned to the position shown in Figure 5 for supplying gasoline from the tank 14 and for shutting ol' the kerosene supply.

The valve 31 can be turned to position for shutting ofi' communication with the pipe 35 and for supplying kerosene to the carburetor, or it may be turned to neutral position. The valve 31 may be controlled readily from the seat of the tractor by means of a suitable control rod.l

It will be seen that where my equipment is used, I am able to do away with and save the expense of the pipe 21 and the valve 22 and do away with the valve 29.

The fuel control may be entirely handled by the manipulation of one valve instead of two, since the valve 31 may be used for supplying kerosene or gasoline or for shutting of the supply from both kerosene and gasoline tanks.

The valve 31 serves all the purposes of the valve 22 and the valve 29.

Furthermore by arranging the arts, as shown in my combination, the fuell always travels through the coil 27, and there is no danger of the coil 27 being overheated or burned out.

My construction is simpler than that heretofore employed, uses less material and fewer parts, requires fewer operations for its complete range and manipulation and requires less care.

For instance, with the old construction, when the operator leaves the tractor, he must turn the valve 22 to neutral position and also shut oll the valve 29. The latter operation is to prevent the Hooding of the carburetor and the wasting of the kerosene.

With my apparatus, he simply turns the valve 31 to neutral and no further attention is required.

I claim as my invention:

In combination with an engine having an intake and exhaust manifold, a kerosene tank, a gasoline tank, a carburetor, a coil in the exhaust manifold, communicating with the intake manifold and the carburetor, and a valve casing havin a three-way valve therein mounted on said carburetor and arranged to communicate therewith, pipes leading from the kerosene tank and the gasoline tank to said casing, the parts being so arranged that by manipulation of said valve, communication may be established between the kerosene tank and the carburetor, or communication may be established between .the gasoline tank and the carburetor or the supply of gasoline and kerosene may both be shut off.
